Objective To analyze the efficacy and safety of different acupuncture methods on outcome of in vitro fertilization-embryo transfer (IVF-ET). Methods The PubMed, EMbase, Cochrane Library, CNKI, VIP, WanFang Data and CBM databases were searched to collect randomized controlled trials (RCTs) related to the objectives of the study from the inception to April 16, 2023. After two investigators independently screened the literature, extracted the data and evaluated the risk of bias of the included studies, a network meta-analysis was performed using Stata 16.0 software. Results There were 62 trials total with 9844 patients, involving 7 interventions. Network meta-findings analysis revealed the following: ① Clinical pregnancy rate (CPR): needle warming > auricular acupressure > transcutaneous electrical acupoint stimulation (TEAS) > electroacupuncture > acupuncture > sham acupuncture > no adjunctive treatment; ② Live birth rate (LBR): electroacupuncture > auricular acupressure > TEAS > acupuncture > sham acupuncture > no adjunctive treatment. Conclusion?Needle warming assisted IVF-ET is superior to other acupuncture therapies in improving CPR, especially during the promotion period of excretion, and the selection of Zusanli, Guanyuan and uterine acupoints for 3-month cycles may have the best effect. And for the LBR, the effect of electroacupuncture is better than that of other therapies. Besides, auricular acupressure may have good therapeutic potential. Due to the limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusions.
